I know this is a very popular isseu but, I cant seem to setup my email, and its getting very fustrating. I no for a fact I have the correct server and port numbers but i keep getting this message. Im fairly new at this as you can see!!

You will then need to delcare where you are sending the email from:HELO local.domain.name - dont worry too much about your local domain name although you really should use your exact fully qualified domain name as seen by the outside world the mail server has no choice but to take your word for it as of RFC822-RFC1123.This should give you:250 mail.domain.ext Hello local.domain.name [loc.al.i.p], pleased to meet you

Have you checked to make sure that the POP3 sever is actually running on the server? I assume you are on Exchange 2003, but I think 2007 is off by default as well.

I would re-check all the server protocol settings for your POP3 virtual server, Ports, service enabled, etc.

I would then look to your FW and make sure all your NATing is correct. Sounds like you are forwarding 510 to the mail server. Is the server listeing on 510?Are packets arriving at the server and on the right port?

Not an answer, but a workaround. I'm running Exchange 2007, and I gave up after many attempts. Simple workaround: set up a POP3 account @ my ISP support@mycompany.co.uk . Not ideal, but at least its working till it integration is simplified.

Is your spiceworks system outside your network?? My questioning is because if the system is on the same network as your email server then you should not be using the ports that are on your firewall but the actual ports that are on your email server. I have an Exchange 2003 server so I use port 25 for the SMTP and port 110 for the POP side, internally of course. Different ports for crossing the firewall for encryption.
